DOOR CHECK AND SPRING.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed January 11, 1.904. `Serial No. 188.476.

To all whom t may concern.-

Beit known that I, VICTOR BEAUREGARD, a citizen of the United States, residing at Roxbury, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Door Checks and Springs, of which the following is a specification.

This invention relates to door checks and springs, and is anv improvement upon the door check and spring for which Letters Patent were issued to Victor Beauregard and Charles S. GoodingJulyZS, 1903, No. 734,658, the particular improvement being a convenient and simple means for increasing or diminishing the tension of the spring in said device, and further improved means by which the checkin -cylinder and the bracket yto which said cy inder is attached are prevented from rotating one with relation to the other when strain is brought to bear upon the parts during the operation of the check.

The invention consists in the combination and arrangement of parts set forth in the following speciflcation, and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a front elevation of my improved door check and spring, a portion of the door and casing being indicated in dotted lines. Fig. 2 is a plan view of the same, a portion of the door and casing being indicated in dotted lines. Fig. 3 is a vertical section, partly in elevation, taken on line 3 3 of Fig. 2 looking toward the left. Fig. 4 is a horizontal section, partly in elevation, taken on line 4 4 of Fig. 1. Fig. 5 is a front elevation of my improved spring-winding sleeve. Fig. 6 is a plan view of the same, a spring-winding wrench being illustrated in dotted lines in connection therewith. Fig. 7 is a detail section taken on line 7 7 of Fig. 2 looking toward the left in said figure.

As the construction of the check and spring throughout is substantially the same as that shown and described in said Letters Patent hereinbefore referred to, with the eX- ception of the means by which the spring is wound and the means by which the sheetmetal bracket, journal-bearing bracket, and cylinder are prevented from rotating with relation to each other, a detailed description of all .the parts and their relative movements is not necessary.

In the drawings, 10 is a pneumatic cylinder, screw-threaded at its opposite ends to receive, respectively, a cap 11 and a journalbearing bracket 12. The cylinder 10 is partially encircled by a sheet-metal clampbracket 13, constructed to be attached by screws to the door 14 or the door-casing 15. To prevent thel rotation of the cylinder 10 and bracket 12 upon the sheet-metal bracket 13, a projection 16 is provided upon said sheet-metal bracket, Figs. 1 and 7, which is constructed to project into either one of the recesses 17, 18, or 19. When the projection 16 extends into the recess 17, as'shown in Fig. 1, the dierent parts of the check are in proper position with relation to each other to be fastened to a door. When the projection 16 projects into either one of the recesses 18 or 19, the check is in proper position to have the metal clamp-bracket 13 attached to the door-casing and the arm to the door. The clamp-bracket 1'3 is clamped to the cylinder 10 by clamp-screws 20.

The journal-bracket 12 has a sleeve 22 fast thereto and preferably integral therewith, which forms a bearing for a journal-stud 23, integral with the closed end 24 of the cylindrical spring-casing 25. The spring-casing 25 is adapted to rotate upon the journal-bearing bracket 12 and is rotated thereon by an arm 26, provided with a rectangular shank 27, which projects through a hole provided in the spring-casing 25 and extending longitudinally through the journal-stud 23. (See Fig. 3.) p spring-casing by means of a washer 29 and split pin 30. When it is desired to reverse the relative position of the arm 26 and springcasing 25, or, inother words, if it is desired to fasten the arm 26 to the lower end of the casing 25 instead of to the upper end thereof, as shown in Fig. 1, the split pin 30 is withdrawn from the shank 27 the washer 29 is removed from said shank,and the arm 2.6, together with its shank 27 is drawnupwardly out of the casing 25, the arm turned upside down' from the position shown in Fig. 1, and the shank 27 inserted in the casing 25 at the lower end of said casing, so that the arm is then beneath the casing and the shank projects u wardly therefrom through said casing. rIhe washer 29 is then placed upon the upper end of the shank in its new position and the split pin 30 inserted in the hole provided therefor in the end of the shank, thus fastening the arm to the opposite end of the Said arm and shank are held in the IOO casing from that to which it is shown as fastened in Figs. 1 and 3. The outer end of the arm 26 is connected by an adjustable link 52 to a bracket 28, fast to the door or door-casing, as the case may be and as hereinafter more fully set forth. The link 52 is pivotally connected at 31 to the bracket 28 and at 32 to the arm 26. The piston 33, of any desirable construction, and the piston-rod 34 are adapted to reciprocate in the interior of spring-winding sleeve 40, constructed to be adjustably rotated upon the sleeve 22, forming a portion of the bracket 13.

The spring-winding sleeve 40 has a cylindrical iange 41 integral therewith and projecting outwardly therefrom to the periphery of the spring-casing 25. Said flange is provided with recesses 42, which serve a double purpose, one of said urposes being to receive the end of a loc {ing-pawl 43, pivoted at 44 to the bracket 12, and thus lock the spring against unwinding, the second purpose of said recesses being to receive a wrench 45, by means of which the spring-winding sleeve 40 may be rotated and the spring wound up or unwound, as may be desired.

The general operation of the check in the opening and closing of a door and the construction by means of which the same is attached to a right or left hand door on the side of the hinges or on the opposite side therefrom is the same as in said patent hereinbefore referred to.

The manner of operating the spring-winding device, hereinbefore specifically described, is as follows: The wrench 45 is inserted in one of the recesses 42 and turned in the proper direction to wind up or unwind the spring 38, as may be desired, the pawl 43 being removed from engagement with the recesses 42 in order to allow ofthe spring being vwound up or unwound, and when the desired tension has been obtained the stop-pawl 43 is again thrown into engagement with the recesses 42. It will be seen that this means of winding the spring is very convenient and practical for any position in which the check may be placed and without disconnecting any of the other parts of the check in order to allow the spring to be wound up or unwound, so that the tension of the spring may be readily increased or diminished to suit varying conditions of wind -pressure, &c.,

bracket 28 fast to the door-casing.

upon the door, or all tension may be removed from the spring, if desired-as, for instance, in cases where a store-door is desired to be left open upon a warm pleasant day.

The operation of the projection 1 6 in connection with the recesses 17, 18, and 19 is as follows: Assuming' the projection 16 to be in the position shown in Fig. l-that is, projecting into the recess 17-then the check is in position to be placed upon a door with the bracket 13 screwed to the door and the Now assuming that it is desired tol place the check on the side opposite the hinges with the clamp-bracket 13 screwed to the casing and with the bracket 28vfast to the door, then the clamp-screws 20 arereleased sufficiently to allow the bracket 13 to be rotated upon the cylinder 10, said bracket being first moved toward the right, Fig. 1, until the projection 16 passes out of the recess 17. The bracket 13 is then rotated until the projection 16 comes opposite the recess 18 or 19, as may be desired. Said bracket is then moved toward the left until the projection 16 enters one of said recesses, and upon tightening the clampscrews 20 the device is in condition to be attached to the door-casing of a right or left hand door, as the case may be, and the bracket 12, cylinder 10, and clamp-bracket 13 are held in fixed relation to each other, so that said clamp-bracket 13 will not rotate upon the cylinder 10.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-

1. A door-closing mechanism comprising in its construction a journal-bearing bracket constructed to be'attached to a door or ldoorcasing, a spring-casing journaled to rotate upon said bracket, an arm fast to said casing, means to connect said arm to a door-casing or door, a spring-winding sleeve constructed to be rotated independently of said other parts, means to lock said sleeve to said bracket, and a spring one end held by said casing the other by said sleeve.
